Northern region-Very wet and rocky, very unsuitable for farming but was very into shipbuilding and fishing
middle region- also known as the bread basket and was very suitable for farming whet and other grains
Southern region- VERY MOIST. Swamps everywhere and very hot. Tobacco was the main cash crop
The answer is wheat. Wheat was one of the most exported products in the US because of its abundance. North America owns the largest fertile lands in the world. They make up 50 percent of the kernel production in the world. Wheat was being exported during the 19th century because most countries like Russia, Great Britain can not grow such product because of its climate and geographical location.
The only people allowed to vote was Wealthy land-owners who were white and male. If you were not all these, you were disqualified. I hope this helps!
